Show details and diff for a specific commit.
AI agents call git_show_commit to retrieve information from DevToolkit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The git_show_commit tool retrieves and displays historical commit information (details and diffs). It does not modify repositories, execute code, or trigger external operations. This is a standard Git inspection operation with no side effects, fitting clearly into the Read category.
From the tool's definition Tool name is 'git_show_commit' and description states it 'Show details and diff for a specific commit' — this is a read-only query of version control metadata and diffs, with no modification or execution capability.
Attacks that exploit this kind of access
Show details and diff for a specific commit. It is categorised as a Read tool in the DevToolkit MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DevToolkit MCP Server MCP server in PolicyLayer and add a rule for git_show_commit: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DevToolkit MCP Server. Nothing to install.
git_show_commit is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the git_show_commit rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for git_show_commit. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
git_show_commit is provided by the DevToolkit MCP Server MCP server (tusharrayamajhi/devtoolkit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
